A new addition to my personal library, thanks to Bluesky's #visionscience community (even if in the sequence of a sad new).

Thank you all for the great feedback and insightful questions on my poster "Exploring Action-Specific Effects: A Representational Momentum Study of the ‘Pong Effect’" at #ECVP2025. It was a wonderful conference and I am already looking forward to the next one!

Shout-out to Rodrigo Freita's presentation of our work "Dynamic events as a natural cause for the Onset Repulsion Effect" at #ECVP2025. We had a great feedback and fruitful discussions.

Yesterday was our "Illusion Day", with interactive demonstrations of classic perceptual illusions made by my students of Attention&Perception. It was the first time I attempted this activity with a class and it was definitely a success! Will repeat it next year! (more illusions in the comments)

It is my conviction that the time required for a Matlab script to finish is directly proportional to its understandability (or, stated differently, the most efficient scripts are necessarily more obscure and harder to understand)

This is the output of my modest Matlab implementation of Marr&Poggio's cooperative algorithm for stereo disparity.
With less than 100 lines of code, it is not efficient, the parameters need to be tweaked for each simulation and only works in Flatland, but it makes the core ideas clear for students.

Trumps' administration rescinded a program with Portuguese Universities (including the one where I work) along with a questionnaire on ideological issues (women's rights, equity, inclusion, global warming, etc), hinting that continuation of the program hinges on giving the "right" answers... 😡
Questionário da Administração Trump também foi recebido pela FLUL, com perguntas sobre “agendas climáticas”, “contactos com partidos comunistas e socialistas” e relações com ONU, China, Irão e Rússia.

In preparation for my Perception class this next week, on lightness and colour constancy, I made a cardboard model of the 1977 Gilchrist's experiment.

Right - view through the pinhole (the white target now seems black)

Like much of the world, I’m struggling to make sense of Trump right now.
Is it the minerals? Then he’s just greedy.
Zelensky’s popularity? Then he’s petty and envious.
Putin’s leverage? Then he’s a coward.
A MAGA stunt? Then he’s just a clown.
The saddest part? It is probably all of the above...

In response to Trump's actions, I've seen lots of comments like "Can you imagine if it was Biden?".
Well, yes, yes I can imagine! And not seeing any reaction anywhere near what I can imagine is baffling!
Granted, I'm following all this from afar and through the lenses of social media, but still...

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

The U.S. anti-science movement is going forward full force. Withdrawal from the Paris Agreement, an anti-vaxxer as Secretary of Health, and now this?
"Officials halted midstream a training workshop for junior scientists, called off a workshop on adolescent learning minutes before it was to begin, and canceled meetings of two advisory councils."
It could've been telegraphed in advance. The fear, uncertainty, chaos, and disruption are the point.

Based on my previous papers, the word 'the' is ~7% of my manuscripts; the word 'of' ~5% and the word 'and' ~4%. The words 'in', 'to', 'for' and 'with' add up to ~8%.
Thus, 24% of my next manuscript is already written, without even opening the text editor! What a productive morning! 😅
